SPECIFICATION forming part of Letters Patent No. 516,877, dated March20, 1894.

Application filed December 9, 1893.

T0 all wir/0m it may concern.-

Be it known that I, HERMAN ROTTER, a subject of the Emperor ofAustria-Hungary,hav ing resided in the United States one year last past,and declared my intention of becoming a citizen thereof, residing in thecity and county of Philadelphia, State of Pennsylvania, have invented anew and useful Improvement in Vashboilers, which improvement is fullyset forth in the following specification and accompanying drawings.

My invention consists in providing a wash boiler with means wherebyclothes, garments or other articles to be washed are subjected both tothe action of boiling water and steam, the construction and operation ofparts being hereinafter set forth.

Figure l represents a top or plan view of the interior of a wash boilerembodying my invention. Fig. 2 represents a vertical section thereof online ir, az, Fig. l. Fig. 3 represents an irregular horizontal sectionon line y, y, Fig. 2.

Similar letters of reference indicate corresponding parts in the severalgures.

Referring to the drawings: A designates a Wash boiler or the bodythereof, and B designates a steam chamber or generator which dependsfrom the bottom C of the boiler, and is in communication with thecylindricalor other tubular-shaped column D, which rises from saidgenerator and extends to nearly the top of the boiler where there isplaced over it the sages from said column, and has secured to its endsthe roses F which extend obliquely, so as to open downwardly, and injectsteam toward the bottom of the boiler.

G designates a false bottom which is supported above the bottom C, andhas connected with it the cone H, which encircles the column D, and hasits upper end closely contacting with the top of said column, so thatthere is no direct communication between the column and cone, it beingnoticed thatthe deector E and roses F are secured to the upper end ofthe cone. The bottom G and said cone H are perforated for thecirculation of water The operation is as follows: The cone is re- SerialNo. 493,210. (No model.)

moved, and with it the bottom G, the deliector E and roses F. The top ofthe column is now uncovered, and a quantity of Water poured ,intosaid/column. Water is also placed in the boiler A, and the cone withconnected parts restored to its operative position. The clothes, dac.,are soaped or otherwise prepared and placed in the boiler, and thedevice suitably located on a stove, range, dvc., so that steam isgenerated in the column D, and the 6o water in the bottom of the body Abrought to a boil. As the steam rises in the column D it reaches thedeflector E, and is directed by the same to the roses F, where it isinjected upon the clothes, &c.

It will be observed that the clothes, &c., are subjected to the boilingwater from below, and as the water and steam mingle and circulatethrough the cone and false bottom, it is evident that the clothes, dac.,are subjected to the 7o combined action of steam and water, and thuseffectively boiled, it being also evident that dirt and sediment whichpass through the false bottom G, will owing to the inclined upper wallof the heater, settle on the bottom C 7 5 so that but a small quantitywill enter the said heater and the column D, and thus clean steam isconstantly directed upon the clothes, &c. Furthermore, the false bottomsustains the clothes,&c., above the bottom C, whereby 8o they areremoved from the fire and prevented from being burned. When the water inthe generator and cone has been entirely converted into steam, theboiling is believed to,Y be completed.

` In order to prevent the column D from being emptied of water, and thuscause burning of the bottom thereof, I form openings in the inclined topor upper wall of the heater B of the boiler, so that water from theboiler 9o proper may enter said heater and circulate therethrough, sothat as long as there is any water in the boiler, there will also bewater in the heater, the effect of which is evident.

Having thus described myinventiomwhatl 9 5 claim as new, and desire tosecure by Letters Patent, is

1. A steam generator, and a communicating column rising therefrom, and aperforated false bottom with a perforated cone rising roc connected Withthe bottom thereof, and having an inclined. upper perforated Wall, anupward rising column from said heater, a hood for said column, a falsebottom in said boiler, a perforated cone connected with said falsebottom, and encircling said column, and roses connected with said hood,said parts being combined substantially as described.

HERMAN ROTTER.
